About 7:50 p.m. they located her vehicle.

She was pronounced dead at the scene.

Troopers from the Grants Pass worksite and Central Point Area Command are completing the investigation to determine the main cause of the crash.Josephine County Sheriff’s deputies, Oregon Department of Transportation personnel, and emergency responders with both Wolf Creek and Rural Metro Fire Departments assisted at the scene.
